Terbium was discovered in 1843 by C.G. Mosander in Stockholm and was named after the Swedish town of Ytterby. A lanthanide group metal, it is soft, malleable and ductile. Terbium has an abundance of 1.1 ppm in the earth's crust and is found in minerals in combination with other lanthanide group elements. It is slowly oxidized in air, the rate of the reaction being increased if terbium powder is used. Terbium reacts slowly with cold water. Terbium is used in the semiconductor industry as a dopant.

magnify Click to zoom!

Terbium sulfate Tb2(SO4)3 - octahydrate, is an important colourant in glass manufacturing and porcelain enamel glazes. High purity Terbium Sulfate is applied as dopant in making optical fibre, lasers and amplifiers such as phosphors and halide lamps.

Here you get a mini-ampoule (25mm length + 6mm diameter) with an amount of 0.3 - 0.4 grams Terbium sulfate crystals (0.5 - 2mm) - Depending on the sort of light you get different colors of the solution and crystals:

  • White at normal light
  • light green under ultraviolet light (money checker etc.)
